Anti-frost heaving pile foundation for installing photovoltaic support in frozen soil area and construction method of anti-frost heaving pile foundation
The invention discloses an anti-frost heaving pile foundation for installing a photovoltaic support in a frozen soil region and a construction method of the anti-frost heaving pile foundation, and belongs to the technical field of pile foundations in frozen soil regions. The anti-frost heaving pile foundation comprises a photovoltaic support, a prefabricated pipe pile, a support connecting section, an anti-frost heaving section and a fixing section. The support connecting section is located above the prefabricated pipe pile and used for connecting the photovoltaic support and the pile foundation. The anti-frost-heaving section is filled with an anti-frost-heaving material, so that the influence of soil body frost heaving on engineering is eliminated, and the effect of resisting soil body frost heaving is achieved; the fixed section is located at the lower end of the prefabricated pipe pile and plays a role in improving the stability and pulling resistance of a pile body. The construction method comprises the steps of hole digging, hole cleaning, core inserting concrete pouring, pile shoe positioner mounting, vibration pile planting, centering positioner mounting, frost heaving resisting material and sleeve filling, core filling concrete pouring and the like. The problem that time and labor are consumed in an original pile periphery frost heaving soil replacing and filling technology is solved, the time spent on pile body maintenance can be saved through selection of the prefabricated pipe piles, and therefore the construction progress is accelerated.
本发明公开了一种冻土区光伏支架安装用抗冻胀桩基础及其施工方法，属于冻土区桩基础技术领域。该抗冻胀桩基础包括光伏支架、预制管桩、支架连接段、抗冻胀段和固定段，支架连接段位于预制管桩上方用于连接光伏支架与桩基础；抗冻胀段中填充抗冻胀材料消除了土体冻胀对工程的影响，并起到了抗土体冻胀的作用；固定段位于预制管桩下端起到提升桩身稳定性和抗拔力的作用；该施工方法包括：挖孔、清孔、浇筑插芯混凝土、安装桩靴定位器、振动植桩、安装居中定位器、填充抗冻胀材料、套筒和浇筑填芯混凝土等。本发明解决了原有桩周冻胀土换填技术耗时耗力的问题，并且预制管桩的选用可以省去由于桩身养护所花费的时间，从而加快施工进度。
